Effect of oxidative treatment on the secondary structure of decoloured bloodmeal [PDF]

open access: yes, 2014
Bloodmeal can be decoloured using peracetic acid resulting in a material with a pale-yellow colour which only needs sodium dodecyl sulphate, water and triethylene glycol to extrude into a semi-transparent bioplastic.

Heterogeneous reactions of particulate matter-bound PAHs and NPAHs with NO3/N2O5, OH radicals, and O3 under simulated long-range atmospheric transport conditions: reactivity and mutagenicity. [PDF]

open access: yes, 2014
The heterogeneous reactions of ambient particulate matter (PM)-bound polycyclic aromatic hydrocarbons (PAHs) and nitro-PAHs (NPAHs) with NO3/N2O5, OH radicals, and O3 were studied in a laboratory photochemical chamber. Ambient PM2.5 and PM10 samples were

Oxidative stress: oxidants and antioxidants [PDF]

open access: yesExperimental Physiology, 1997
An imbalance between oxidants and antioxidants in favour of the oxidants, potentially leading to damage, is termed ‘oxidative stress’. Oxidants are formed as a normal product of aerobic metabolism but can be produced at elevated rates under pathophysiological conditions. Antioxidant defense involves several strategies, both enzymatic and non‐enzymatic.

Functions of Redox Signaling in Pollen Development and Stress Response

open access: yesAntioxidants, 2022
Cellular redox homeostasis is crucial for normal plant growth and development. Each developmental stage of plants has a specific redox mode and is maintained by various environmental cues, oxidants, and antioxidants.
